Sick ISIS terrorists have burned four men to death in their latest graphic video

The brutal militant group released the video of the four Iraqis’ deaths after accusing them of spying for rival Shiite militia.

The men are seen stating their names and alleged crimes on camera before being chained around their wrists and ankles and suspended in the air.

A line of fuel has been poured underneath the blindfolded men and masked militants set fire to their captives in the Iraq’s western Anbar province. The gruesome video shows slow motion footage as the fire burns up the fuel and the men are agonizingly burnt to death, the Independent reports.

The men are forced to confess their alleged crimes to camera before their deaths.

They were reportedly made to watch footage of Islamic State militants’ bodies supposedly being mutilated by Iraqi soldiers.

In the video, the Iraqi soldiers reportedly watch the ISIS militant’s body is burned.

This incident comes a week after a video of Shiite militia leader Abu Azrael (not pictured) burning an Islamic State fighter over a pit circulated online.

Last week, a video circulated on social media showed the Shiite militia leader Abu Azrael, known as the "Angel of Death," torturing and killing an alleged ISIS fighter by burning him alive over an open pit.
